Local Quantum-Criticality in the Dissipative XY-Model in 2D

Quantum critical fluctuations in which the time-dependence is scale invariant but the spatial dependence is local stand in contrast to the paradigm of classical dynamical critical phenomena and its simple quantum generalization. There is experimental evidence for them near the quantum critical point both in cuprates and near the Anti-ferromagnetic critial point in Fe-based superconductors and in some heavy Fermions. The dissipative Quantum XY-Model, proposed initially to describe the superconductor to insulator transition in thin films, with an anisotropic generalization, describes both. I will summarize an analytical solution of the model which derives local quantum critical fluctuations for this model as due to the proliferation of a class of topological exciations and supplement it by Monte-Carlo calculations on the model.

Pomerons, Holograms, and "Practical" String Theory

I will describe a model for Pomeron-mediated scattering in holographic QCD. After reviewing Regge theory, the Pomeron, and holographic QCD, I will discuss a strategy for constructing Regge-regime hadronic scattering amplitudes, including specific predictions for proton-proton scattering. I will also discuss central production of mesons in these processes.

Effective potentials and morphological transitions for binary black-hole spin precession

Generic binary black holes have spins that are misaligned with their orbital angular momentum. When the binary separation between the black holes is large compred to their gravitational radii, the timescale on which the spins precess is much shorter than the radiation-reaction time on which the orbital angular momentum decreases due to gravitational-wave emission. We use conservation of the total angular momentum and the projected effective spin on the precession time to derive an effective potential for BBH spin precession. This effective potential allows us to solve the orbit-averaged spin-precession equations analytically for arbitrary mass ratios and spins. These solutions are quasiperiodic functions of time: after a precessional period the spins return to their initial relative orientations. We classify black-hole spin precession into three distinct morphologies between which the black holes can transition during their inspiral. Our new solutions constitute fundamental progress in our understanding of black-hole spin precession and also have important applications to astrophysical black holes. We derive a precession-averaged evolution equation that can be numerically integrated on the radiation-reaction time, allowing us to statistically track black-hole spins from formation to merger. This will greatly help us predict the signatures of black-hole formation in the gravitational waves emitted near merger and the distributions of final spins and gravitational recoils.

Stochastic Thermodynamics, From ħ=0 to ħ=1

Progress has been made during the last decades in the development of a statistical theory for classical out-of-equilibrium system. In addition to celebrated fluctuation theorems, stochastic thermodynamic now provides both a nice unifying theoretical framework and a useful way for studying these systems experimentally. It was for instance at the heart of the first experimental verification of Landauer principle. After reviewing the classical case, I will propose an attempt to construct a quantum stochastic thermodynamics based on a quantum trajectory description of driven open systems. This framework allows for definitions at the single trajectory level of basic thermodynamic quantities such as heat transfer, work and entropy in the quantum regime. It can then be used to obtained “central” fluctuation theorems, from which follow more"practical" fluctuation relations such as for instance Jarzynski and Crooks fluctuation theorems. I will discuss in particular similarities and differences between the ħ=0 and ħ=1 regimes.

Constraining Galaxy Feeding and Feedback with MaNGA

A central issue in galaxy evolution is understanding the "baryon cycle," namely how gas is accreted onto galaxies and expelled in galactic winds. Gas flows are difficult to measure directly, but disk galaxy nebular oxygen abundance measurements can provide powerful indirect constraints. I will present some early work form the SDSS-IV MaNGA survey which will obtain spatially resolved oxygen abundance measurements of around 5,000 disk galaxies.
